Using ABS
To obtain the maximum benefit from
your ABS in an emergency situation,
do not attempt to modulate your
brake pressure and do not try to
pump your brakes. Depress your
brake pedal as hard as possible.
When you apply your brakes under
conditions which may lock the
wheels, you may hear sounds from
the brakes, or feel a corresponding
sensation in the brake pedal. This is
normal and it means your ABS is
active.
ABS does not reduce the time or dis-
tance it takes to stop the vehicle.
Always maintain a safe distance from
the vehicle in front of you.
ABS will not prevent a skid that
results from sudden changes in
direction, such as trying to take a
corner too fast or making a sudden
lane change. Always drive at a safe
speed for the road and weather con-
ditions.ABS cannot prevent a loss of stabili-
ty. Always steer moderately when
braking hard. Severe or sharp steer-
ing wheel movement can still cause
your vehicle to veer into oncoming
traffic or off the road.
On loose or uneven road surfaces,
operation of the anti-lock brake sys-
tem may result in a longer stopping
distance than for vehicles equipped
with a conventional brake system.
The ABS warning light ( ) will stay
on for several seconds after the
Engine Start/Stop button is in the ON
position. During that time, the ABS
will go through self-diagnosis and the
light will go off if everything is nor-
mal. If the light stays on, you may
have a problem with your ABS.
Contact an authorized HYUNDAI
dealer as soon as possible.
If the ABS warning light ( ) is
on and stays on, you may have a
problem with the ABS. Your
power brakes will work normally.
To reduce the risk of serious
injury or death, contact your
HYUNDAI dealer as soon as pos-
sible.

The ESC OFF indicator light comes
on when the ESC is turned off with
the button.
Driving with tires or wheels in var-
ious sizes may fail the normal
operation of the ESC system.
Before replacing tires, make sure
they are in the same size as oth-
ers. Never drive the vehicle, which
is installed with the tires of differ-
ent diameters.ESC OFF usage
When Driving
The ESC OFF mode should only be
used briefly to help free the vehicle if
stuck in snow or mud by temporarily
stopping operation of the ESC to
maintain wheel torque.
To turn ESC off while driving, press
the ESC OFF button while driving on
a flat road surface.To prevent damage to the
transaxle:
Do not allow wheel(s) of one
axle to spin excessively while
the ESC, ABS, and parking brake

are displayed. The repairs would
not be covered by the vehicle
warranty. Reduce engine power
and do not spin the wheel(s)
excessively while these lights
are displayed.
When operating the vehicle on a dynamometer, make sure the
ESC is turned off (ESC OFF light
illuminated).

Hill-Start Assist Control (HAC)
A vehicle has the tendency to slide
backwards on a steep slope, before
depressing the accelerator after a
stop. The HAC helps prevent the
vehicle from sliding backwards by
automatically operating the brake
systems for about 2 seconds. The
brake systems are automatically
released, when the accelerator pedal
is depressed.
Information
• The HAC does not operate when theshift lever is in P (Park) or N (Neutral).
• The HAC activates even when the ESC (Electronic Stability Control) is
off. However, it does not activate,
when the ESC does not normally
operate.

NOTICE
If ESC indicator light ( ) or
EPS warning light ( ) stays
on, your vehicle may have a mal-
function with the VSM system.
When the warning light illumi-
nates have the vehicle checked

er as soon as possible.
WARNING
The HAC is activated only for
about 2 seconds, so always
depress the accelerator pedal
to begin driving upwards after a
stop.
